SeaHawk Flood and Drain Fittings has inlet and outlet fittings. The Inlet is used to pump nutrient into the tray, while the larger Outlet fitting with the extension sits higher in the tray. Once the nutrient level in the tray reaches the height of the Outlet Screen, the excess nutrient can drain back to a reservoir. The extension can be adjusted for more height, and extra extensions can be added for a deeper tray. The Tub Outlet Screen presses into the Tub Outlet or Tub Outlet Extension to help prevent large particles passing through the outlet and into the tubing.

The SeaHawk Flood and Drain Fitting Kit comes with:
1 x 25mm Tub Outlet
1 x 19mm Tub Outlet
1 x 25mm Extension
2 x Screen
